I've seen this kind of shit on 8chan when it was active and some time ago on 4chan I allmost got used to it.This is probably done by a troll, or a group of trolls(usualy there are at least two and they employ a lot of tactics) who migrated here because 8chan/8kun is still fucked up and there are few places where trolls can expand.
I think they started this because both threads of the artists OP and EVMC are dead!
I don't think there is much to be done about it except this:
"The goal of a troll is to engage their victims in an online argument – so the most effective way to deal with them is to ignore them. This may be harder than it sounds, particularly when someone has said something to make you angry."
